It seems I can't save a file twice with the same name
... write basic program ...
save "program",8
... edit basic program ...
save "program",8
(light on floppy blinks - error )
verify "program",8
wont verify
... power cycle ...
load "program",8
... view program ... it's the old program, not the edited program.
this behaviour noted on both a read c64sx (before it croaked) and on
the VICE emulator.
I can't seem to see anything in the manual about it.. and also no
command to delete a file.
